Is an exhaust fan permitted in the shower? My customer has a shower that is totally separated by a wall and shower door from the bathroom area. Also I assume I can put a recess light with a gasket in the shower. Does it have to be on GFI circuit. I'm only looking at the 99 code and do not have the newer ones available right now. Thanks..

Not a problem Sparky, But you need to look at the Listing. The fans that are suitable for use in a shower will be labeled "Suitable for use in a shower when installed on a GFCI protected circuit" or word to that effect. Beyond that you could be asking for trouble.

On the fan subject.We in oregon have had some changes.Bathrooms that have bathing facilities must have a min 80cfm max 3 sone controled by a timer,humidistat or auto control. Ducting to be smooth wall,no flex. This applies also for fan replacements.
